Description
Technical field
A kind of reactive dye contaminate cellulose fibre low temperature soaping technique, belong to fiber and soap technical field.
Background technique
Reactive dye have the advantages that it is bright in luster it is good, chromatography is complete, price is lower and dyeing is mature.But activity dye
There is also certain disadvantages for material, such as while with fiber-reactive, it may occur that hydrolysis, hydrolised dye generally cannot be again and fine
Dimension reacts, and causes the utilization rate of dyestuff lower.And not upper dye dyestuff and hydrolised dye present on fabric, it need to be by soaping
It removes, otherwise will affect dyefastness, especially deep heavy colour fabric.The tradition of Fabrics Dyed with Reactive Dyes technique of soaping generally exists
95 DEG C or more, temperature is high, and the time is long, and washing times are more, and technique is cumbersome, and water consumption energy consumption is high.Therefore, it develops under cryogenic just
Soaping agent with effect of preferably soaping becomes a big target of dyeing and finishing industry.
Summary of the invention
The technical problem to be solved by the present invention is overcome the deficiencies of the prior art and provide a kind of short process time, water consume,
The reactive dye that low energy consumption contaminate cellulose fibre low temperature soaping technique.
The technical solution adopted by the present invention to solve the technical problems is: the reactive dye contaminate cellulose fibre low temperature soaping
Technique, which is characterized in that process curve are as follows: first in 50 DEG C of 8 min of low temperature soaping liquid wash-in ~ 11min, then with 1.7 DEG C/min
The heating rate of ~ 2.2 DEG C/min rises to 58 DEG C ~ 63 DEG C, keeps the temperature 18 min ~ 23min, is then down in 9min ~ 12min often
Temperature；In the liquid of soaping compound low temperature soaping agent mass concentration be 1.8g/L ~ 2.2g/L, low temperature soaping liquid pH value be 8 ~
10。
The inventors found that after pure cotton knitted fabric reactive dyeing, tradition is soaped in technique with temperature of soaping
Raising, raffinate total absorbance of soaping is continuously increased, when soap 80 DEG C of temperature when raffinate total absorbance of soaping it is maximum, and soap
Temperature raffinate total absorbance of soaping when reaching 95 DEG C declines instead.Inventor thinks before 80 DEG C, with the raising for temperature of soaping,
The dyestuff that soaping agent removes is more than the dyestuff that oxidant is degraded, therefore absorbance increases；At 95 DEG C, oxidant can degrade more
Dyestuff, therefore raffinate absorbance reduce.So tradition living is soaped, the tradition of technique neutral dyeing fabric technique of soaping is general
At 95 DEG C or more.The specific compounding low temperature soaping agent of process curve cooperation of the invention, can at a temperature of lower soap,
Reach effect of more preferably soaping in the shorter time.
Mass concentration of the compounding low temperature soaping agent in liquid of soaping is 1.9g/L ~ 2.0g/L.Compound low temperature soaping
The use concentration of agent can large effect soap effect, the preferred low temperature soaping agent dosage that compounds can preferably guarantee to soap
Raffinate total absorbance is small, and color fastness is high.
The parts by weight group of the compounding low temperature soaping agent becomes 0.8 ~ 1.2 part of maleic acid-acrylic acid copolymer, oxidant
23 ~ 27 parts, 4.5 ~ 5.6 parts of urea, 0.7 ~ 1.2 part of sodium metasilicate.The compounding low temperature soaping agent that the present invention matches can be lower
At a temperature of to soaping after pure cotton knitted fabric reactive dyeing, raffinate total absorbance of soaping is small, and k ∕ s value reaches a high temperature soap
Effect is washed, colour fastness to rubbing, water-fast boiling hot color fastness and fastness to soaping are improved.
The parts by weight group of the compounding low temperature soaping agent becomes 0.9 ~ 1 part of maleic acid-acrylic acid copolymer, oxidant 25
~ 26 parts, 4.8 ~ 5.2 parts of urea, 0.9 ~ 1.1 part of sodium metasilicate.Preferred compounding low temperature soaping agent proportion can be in minimum use
Amount is lower and guarantees raffinate total absorbance minimum of soaping, guaranteed to wash rear fabric colour fastness to rubbing, water-fast boiling hot color fastness and resistance to soap
Wash color fastness highest.
The oxidant is the hybrid oxidant of bleaching powder and potassium permanganate 1:7 ~ 12 in mass ratio.It is provided by the invention
The rate of the degradation of dye of preferred oxidant and the rate of the dyestuff for compounding low temperature soaping agent washout of the invention are preferably suitable
It answers, not only for soaping, raffinate total absorbance is small, and under the premise of guaranteeing fabric color fastness, can reduce and contaminate on fabric
The degradation of material guarantees the color of fabric.Preferably, the oxidant is bleaching powder and potassium permanganate 1:8.5 ~ 10 in mass ratio
Hybrid oxidant.
The temperature of soaping is 60 DEG C ~ 61 DEG C, 19 min of the time ~ 21min that soaps.The present invention provides preferred
Soap temperature and the time of soaping can reach the optimal effect of soaping of the present invention with the highest efficiency of the present invention.
The low temperature soaping liquid pH value is 9.
Compared with prior art, have possessed by a kind of reactive dye of the invention dye cellulose fibre low temperature soaping technique
Beneficial effect is: the dosage that the present invention compounds low temperature soaping agent can preferably guarantee to soap, and raffinate total absorbance is small, and color fastness is high.
The compounding low temperature soaping agent that the present invention matches can be at a lower temperature to carrying out soap after pure cotton knitted fabric reactive dyeing
It washes, raffinate total absorbance of soaping is small, and k ∕ s value reaches a high temperature effect of soaping, and colour fastness to rubbing, water-fast boiling hot color fastness and resistance to soaps
Color fastness is improved.The rate of the degradation of dye of oxidant provided by the invention is washed with the low temperature soaping agent that compounds of the invention
The rate of the dyestuff removed well adapts to, and not only for soaping, raffinate total absorbance is small, and is guaranteeing fabric color fastness
Under the premise of, it can reduce the degradation of dyestuff on fabric, guarantee the color of fabric.A kind of specific compounding low temperature is used in the present invention
Soaping agent can reach in a relatively short period of time effect of more preferably soaping at a temperature of lower soap.
